Abstract

In order to allow conductors to be connected to a plug bridge in a simple manner, the plug bridge has a support to which a plurality of contact pins and also a plurality of conductor connections which are electrically conductively connected to, in each case, one contact pin are fastened. The support contains a housing which, together with the conductor connections, is covered by a common dimensionally stable and inherently rigid cover part in a closed state. The cover part has, in the region of the conductor connections, separating webs which extend between the conductor connections in the closed state. The entire dimensionally stable cover part can be moved from an open position to a closed position in a pivotable manner on the support.

Claims

1. A plug bridge for a mains plug, the plug bridge comprising:

a plurality of contact pins;

a plurality of conductor connections;

a support to which said plurality of contact pins and said plurality of conductor connections being fastened, said support having a housing with a plurality of chambers being separated from one another and said conductor connections disposed at an edge next to said housing;

contact tabs, one of said contact tabs electrically conductively connected to in each case one of said contact pins and adjoining one of said conductor connections;

a common dimensionally stable and inherently rigid cover part not having parts that move relative to one another, said cover part covering said housing and said conductor connections, in a closed state, said cover part having separating webs in a region of said conductor connections, said separating webs extending between said conductor connections in the closed state, and in that said cover part on said housing can pivot from an open position, in which said housing is open and said conductor connections are freely accessible, to the closed position such that, during a pivoting movement, said housing is closed and said separating webs are inserted between said conductor connections;

the plug bridge further including at least one articulation element integrally formed on said housing, and said cover part being snapped onto said articulation element, wherein said articulation element is an articulation pin integrally formed on either side of said housing;

said support including a support plate with passage holes formed in said support plate adjacent to said housing; and

said support plate including at least one of;

a casting compound passing through said passage holes in a finally assembled state;

or

an end edge with at least one notch formed in said edge.

2. The plug bridge according to claim 1, wherein said cover part is formed in one piece with said housing.

3. The plug bridge according to claim 2, wherein said cover part is prefabricated with said housing as an injection-molded part in the open position, and said cover part is connected to said housing by a material bridge which fixes said cover part in the open position as an assembly position.

4. The plug bridge according to claim 1, wherein said cover part can be latched to said housing in the closed position for preventing pivoting.

5. The plug bridge according to claim 1, wherein said cover part can be latched to said housing in the open position for preventing pivoting.

6. The plug bridge according to claim 1,

wherein said cover part has a bottom face with at least one first positioning element formed on said bottom face;

and

further comprising a second positioning element, said first positioning element engaging into said second positioning element in the closed position for defined positioning of said cover part relative to said housing.

7. The plug bridge according to claim 6, wherein said second positioning element is a fixing pin for one of said contact tabs associated with one of said conductor connections, said one contact tab being disposed in said housing.

8. The plug bridge according to claim 7, wherein said first positioning element is formed as a closed, hat-like cap.

9. The plug bridge according to claim 1, wherein said conductor connections have said contact tabs which are routed at least partially in or through said housing, wherein at least one of said contact tabs is held on said housing by said housing in an interlocking manner.

10. The plug bridge according to claim 1, wherein said housing and said cover part have, in a manner corresponding to one another, at least one channel and at least one sealing web which engages into said channel.

11. The plug bridge according to claim 10, wherein said housing forms said plurality of chambers with said cover part, and an at least virtually circumferential channel is associated with each of said chambers.

12. The plug bridge according to claim 1, wherein said cover part is connected to said housing in a circumferentially cohesive manner in a finally assembled state.

13. The plug bridge according to claim 1, wherein said cover part is mounted on said housing such that said cover part executes a linear movement in a region of the closed position.

15. A method for producing a plug with an aid of a plug bridge according to claim 1, which comprises the steps of:

connecting conductors to the conductor connections in the open position of the cover part;

moving the cover part to the closed position;

surrounding the plug bridge with a casting compound; and

holding the cover part in a fixed manner in the open position as a mounting position by a material bridge.

14. A plug bridge for a mains plug, the plug bridge comprising:

a plurality of contact pins;

a plurality of conductor connections;

a support to which said plurality of contact pins and said plurality of conductor connections being fastened, said support having a housing with a plurality of chambers being separated from one another and said conductor connections disposed at an edge next to said housing;

contact tabs, one of said contact tabs electrically conductively connected to in each case one of said contact pins and adjoining one of said conductor connections;

a common dimensionally stable and inherently rigid cover part not having parts that move relative to one another, said cover part covering said housing and said conductor connections, in a closed state, said cover part having separating webs in a region of said conductor connections, said separating webs extending between said conductor connections in the closed state, and in that said cover part on said housing can pivot from an open position, in which said housing is open and said conductor connections are freely accessible, to the closed position such that, during a pivoting movement, said housing is closed and said separating webs are inserted between said conductor connections;

said cover part being prefabricated in one piece with said housing as an injection-molded part in the open position, and said cover part is connected to said housing by a material bridge which fixes said cover part in the open position as an assembly position; and

wherein said support includes a support plate with passage holes formed in said support plate adjacent to said housing;

said support plate further comprising at least one of;

a casting compound passing through said passage holes in a finally assembled state;

or

an end edge with at least one notch formed therein.

16. A method for producing a plug with an aid of a plug bridge according to claim 14, which comprises the steps of:

connecting conductors to the conductor connections in the open position of the cover part;

moving the cover part to the closed position;

surrounding the plug bridge with a casting compound; and

holding the cover part in a fixed manner in the open position as a mounting position by a material bridge.
